Abstract

A novel Gram-stain-negative, non-spore-forming, non-motile, facultatively anaerobic, rod-shaped strain, designated XDB06, was isolated from coastal sediment of Xiaoshi Island, Weihai, China. Optimal growth occurred at 37 °C, pH 7.5 and with 4.0 % (w/v) NaCl. Q-8 was the sole respiratory quinone. The major cellular fatty acids in strain XDB06 were iso-C and iso-C. The polar lipids of strain XDB06 were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, two unidentified glycolipids and four unidentified phospholipids. The genomic DNA G+C content of the strain was 65.0 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain XDB06 clusters within the genus and is most closely related to MCCC 1K00261, with a 16S rRNA gene sequence similarity of 96.50 %. Based on data from the current polyphasic study, strain XDB06 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is XDB06 (=KCTC 52041=MCCC 1K02285).
